The evaluation of a pedagogical-program development environment for Novice programmers : a comparative study

It is an acknowledged fact that many novice programmers experience difficulty in the process of learning to program. One of the contributing factors to this difficulty is the Program Development Environment (PDE). Professional-PDEs are those developed specifically for professional programmers, but are often used by educational institutions in the instruction of programming. It has long been accepted that such environments are inappropriate in the instruction of programming due to unnecessary complexity and lack of support for novice programmers in the learning process. Numerous pedagogical-PDEs supporting the mechanics of programming have been developed in response to this. A review of literature, however, indicates that very limited empirical studies comparing pedagogical-PDEs and professional-PDEs have been conducted. The current study investigates whether there are measurable benefits to using a pedagogical-PDE supporting the mechanics of programming in the instruction of programming instead of a professional-PDE. A comparative study of this nature requires a representative pedagogical-PDE and representative professional-PDE be compared with one another. The first part of the current study determines a set of requirements that a pedagogical- PDE should adhere to based on literature. A set of representative features for a pedagogical-PDE is derived by examining the features of existing PDEs in conjunction with the set of requirements. Based on these features, a pedagogical-PDE, known as SimplifIDE, is developed that implements the representative set of features and that meets are the requirements for a pedagogical-PDE. The second part of the current study is the specification and administration of an empirical experiment in which SimplifIDE and Borland© DelphiTM are compared with one another. A holistic approach in determining the differences between the PDEs is taken and three main areas are examined, namely academic performance, perceptions and programming behavior

Introductory programming: a systematic literature review

As computing becomes a mainstream discipline embedded in the school curriculum and acts as an enabler for an increasing range of academic disciplines in higher education, the literature on introductory programming is growing. Although there have been several reviews that focus on specific aspects of introductory programming, there has been no broad overview of the literature exploring recent trends across the breadth of introductory programming. This paper is the report of an ITiCSE working group that conducted a systematic review in order to gain an overview of the introductory programming literature. Partitioning the literature into papers addressing the student, teaching, the curriculum, and assessment, we explore trends, highlight advances in knowledge over the past 15 years, and indicate possible directions for future research

Exploring student perceptions about the use of visual programming environments, their relation to student learning styles and their impact on student motivation in undergraduate introductory programming modules

My research aims to explore how students perceive the usability and enjoyment of visual/block-based programming environments (VPEs), to what extent their learning styles relate to these perceptions and finally to what extent these tools facilitate student understanding of basic programming constructs and impact their motivation to learn programming

An investigation into student reactions towards rad versus traditional programming environments for novice developers

The traditional approach to programming using text editors is widely used in many institutions to teach introductory programming. These types of traditional programming environments provide fundamental programming concepts for learning, especially in the context of novice developers. In recent years, teaching institutions have seen a trend towards the introduction of visual drag-and-drop rapid application development (RAD) environments for teaching novice programmers. These \u27environments capture student interest in programming by allowing the construction of workable programs within a short time frame based on minimal pre-existing coding knowledge. However, some have argued that these visual RAD environments might not be suitable for providing fundamental programming concepts and syntax to novice developers. This research examines student perceptions towards visual RAD environments in comparison to traditional environments for learning programming for novice developers, mainly focusing on the novice developer\u27s first programming environment. To gather student reactions towards these programming environments, surveys, interviews and workshops were conducted with novice, intermediate and expert level student programmers. The results indicate that while visual RAD environments managed to capture the majority of the participants\u27 interest, the traditional approach was largely accepted as the most appropriate first environment for novice developers. Another finding from this research is the participants\u27 perceptions of the key aspects of learning programming, which also formed part of the deciding factors for the first environment. Understanding the underlying concepts, syntax and logic of the program seem to be the most important aspects followed by interest level and the ability to build workable programs quickly. The majority of participants perceived that traditional programming environments could help novice developers with understanding underlying concepts and syntax better than visual RAD environments. Although visual RAD environments do not require a traditional programming environment at the early stage of programming, the latter would become necessary as the program grows and more complex functions are required. Overall, the visual RAD environment was still the preferred environment for development despite the lack of pedagogical benefits compared with traditional environments

An Exploration Of The Effects Of Enhanced Compiler Error Messages For Computer Programming Novices

Computer programming is an essential skill that all computing students must master and is increasingly important in many diverse disciplines. It is also difficult to learn. One of the many challenges novice programmers face from the start are notoriously cryptic compiler error messages. These report details on errors made by students and are essential as the primary source of information used to rectify those errors. However these difficult to understand messages are often a barrier to progress and a source of discouragement. A high number of student errors, and in particular a high frequency of repeated errors – when a student makes the same error consecutively – have been shown to be indicators of students who are struggling with learning to program. This instrumental case study research investigates the student experience with, and the effects of, software that has been specifically written to help students overcome their challenges with compiler error messages. This software provides help by enhancing error messages, presenting them in a straightforward, informative manner. Two cohorts of first year computing students at an Irish higher education institution participated over two academic years; a control group in 2014-15 that did not experience enhanced error messages, and an intervention group in 2013-14 that did. This thesis lays out a comprehensive view of the student experience starting with a quantitative analysis of the student errors themselves. It then views the students as groups, revealing interesting differences in error profiles. Following this, some individual student profiles and behaviours are investigated. Finally, the student experience is discovered through their own words and opinions by means of a survey that incorporated closed and open-ended questions. In addition to reductions in errors overall, errors per student, and the key metric of repeated error frequency, the intervention group is shown to behave more cohesively with fewer indications of struggling students. A positive learning experience using the software is reported by the students and the lecturer. These results are of interest to educators who have witnessed students struggle with learning to program, and who are looking to help remove the barrier presented by compiler error messages. This work is important for two reasons. First, the effects of error message enhancement have been debated in the literature – this work provides evidence that there can be positive effects. Second, these results should be generalisable at least in part, to other languages, students and institutions

Learning to Code: Effects of Programming Modality in a Game-based Learning Environment

As new introductory block-based coding applications for young students to learn basic computer science concepts, such as, loops and conditionals, continue to increase in popularity, it is necessary to consider the best method of teaching students these skills. Many of these products continue to exhibit programmatic misconceptions of these concepts and many students struggle with how to apply what they learn to a text-based format due to the difficulties with learning the syntactic structure not present in block-based programming languages. If the goal of teaching young students how to program is meant to develop a set of skills they may apply when learning more complex programming languages, then discerning how they are introduced to those practices is imperative. However, few studies have examined how the specific modality in which students are taught to program effects how they learn and what skills they develop. More specifically, research has yet to effectively investigate modality in the context of an educational coding game where the modality feature is controlled, and content is consistent throughout game-play. This is mainly due to the lack of available games with this feature designed into the application. This dissertation explores whether programming modality effects how well students can learn and transfer computer science concepts and practices from an educational programming game. I proposed that by being guided from a blocks-based to text-based programming language would instill a deeper understanding of basic computer science concepts and would support learning and improve transfer and performance on new challenging tasks. Two experimental studies facilitated game-play sessions on the developed application for this project. The first study was a 2x2 between subjects design comparing educational module (game versus basic) and programming modality (guided versus free choice). The findings from Study 1 informed the final version design for the module used in the second study where only the game module was used in order to focus the comparison between programming modality. Findings showed that students who coded using the game module performed better on a learning test. Study 2 results showed that students who are transitioned from blocks-based to text-based programming language learn basic computer science concepts with greater success than those with the free choice modality. A comparative study was conducted using quantitative data from learning measures and qualitative video data from the interviews during the challenge task of the second study. This study examined how students at the extreme levels of performance utilized the toggle switch feature during game-play and how the absence of the feature impacted how they completed the challenge task. This analysis showed two different methods of toggle switch usage being implemented by a high and low performing student. The high performing student utilized the resources more often during the challenge tasks in lieu of leveraging the toggle switch and were still able to submit high level code. Results suggest that a free choice student who uses the feature as a tool to check their prewritten code rather than a as short cut for piecing code together as blocks and submitting the text upon the final attempt. This practice leads to a shallower understanding of the basic concepts and make it extremely difficult to expand and apply that knowledge to a more difficult task. This dissertation includes five chapters: an introduction and theoretical framework, a game design framework and implementation description, two experimental investigations, and a quantitative and qualitative comparative analysis. Chapter one provides the conceptual and theoretical framework for the two experimental investigations. Chapter two describes the theory and design structure for the game developed for this dissertation work. Chapter three and four will discuss the effects of programming modality on learning outcomes. Specifically, chapter 3 focuses on implications of programming modality when determining how to implement changes for the design of the game for Study 2. Chapter five discusses a comparative analysis that investigated differing work flow patterns within the free choice condition between high and low performing students. Results from these three chapters illustrate the importance of examining this component of the computer science education process in supplemental games for middle and high school students. Additionally, this work contributes in furthering the investigation of these educational games and discusses implications for design of similar applications

A serious game for programming in higher education

Programming is a highly difficult skill which is a constituent of many undergraduate programmes at Higher Education (HE) level. With the advancement of games technology there is an increasing opportunity for educators to provide innovative assessment tools for students on their courses which are highly immersive and graphically indicative of the times. This could potentially be in a supplementary capacity or to a greater extent inextricably linked to the learning outcomes and assessment outcomes. Notably serious games and Games-Based Learning (GBL) have received high levels of attention from educationalists due to being motivational, novel learning approaches. This paper will outline two empirical studies conducted to develop a game to teach programming at HE level. The first study will gauge the acceptability of a computer game for teaching programming and formulating content integration development requirements. The second study will outline the evaluation of the developed game being placed in a module as a formative assessment tool to assist learners to revise for their formal class test. Study one showed that acceptability of the game was high with 61 participants completing an acceptability/content integration questionnaire. The game was designed to consolidate knowledge on rudimentary and advanced programming concepts, data structures and algorithms. 48 participants evaluated the game in study two with the results generally indicating that they enjoyed playing the game as a revision alternative with 14% of participants rating it as very effective and 51% of participants as effective for allowing them to prepare for their class test. The majority of participants also believed that games could be utilised in a formative and summative assessment capacity on courses for independent study

Visual iconic object-oriented programming to advance computer science education and novice programming

Learning how to program a computer is difficult for most people. Computer programming is a cognitively challenging, time consuming, labor intensive, and frustrating endeavor. Years of formal study and training are required to learn a programming language\u27s world of algorithms and data structures. Instructions are coded in advance before the computer demonstrates the desired behavior. Seeing all the programming steps and instruction code is complicated. There exists a tremendous gap between the representations the human brain uses when thinking about a problem and the representations used in programming a computer. Often people are much better at dealing with specific, concrete objects than working with abstract ideas. Concrete and specific programming examples and demonstrations can be very useful. When cleverly chosen and properly used, programming examples and demonstrations help people understand the abstract concepts. Programming by example or demonstration attempts to extend these novel ideas to novice programming

An evolving approach to learning in problem solving and program development : the distributed learning model

Technological advances are paving the way for improvements in many sectors of society. The US education system needs to undergo a transformation of existing pedagogical methods to maximize utilization of new technologies. Traditional education has primarily been teacher driven, lectured-based in one location. Advances in technology are challenging existing paradigms by developing tools and educational environments that reach diverse learning styles and surpass the boundaries of current teaching methods. Distributed learning is an emerging paradigm today that has promise to contribute significantly to learning and improve overall academic success. This research first explores various systems that provide different modes of learning. The problem domain of this research is the difficulty novice programmers\u27 face when learning to program. This paper proposes how distributed learning can be used in a teaching environment to enrich learning and the impacts for the given problem domain
